Removable partial denture prosthesis are designed as an affordable option for people who need dental implants or a dental bridge. Wear removal partial dentures for six months to a year before switching to a permanent option with advice from a licensed dental assistant in this free video on dentures.

Since when does the dentist actually make the denture? The technician is the one who hand-makes the denture! Any new prosthesis in the mouth is abnormal at first and takes around two days to two weeks for the patient to adjust. It will temporarily affect the normal phonetics and mastication (speech and chewing). Any new object in the mouth feels annoying and uncomfortable until the muscles in the mouth and face adjust to the prosthesis.
* Dentures are delicate and fragile. Try not to drop it when you’re not wearing them.
* Brush your dentures regularly. This will prevent the occurrence of stains and plaque. Use a soft-bristled toothbrush to clean your dentures.
* Some denture wearers use mild hand soap or dish-washing liquid to clean their dentures. These are acceptable alternatives to regular dentures cleaning agents. Avoid using powdered cleansers and bleach as these are too abrasive on dentures.
* Do not let the dentures dry out when you’re not wearing them. It may lose its shape as a result. Soak it in a dental cleanser solution or water instead.Regular dental check-ups are also important. Your dentist needs to examine your dentures to see if they fit properly and if the dentures need to be relined, rebased or replaced due to normal wear. Loose and ill-fitting dentures breed infections and mouth sores. So the minute you feel discomfort in your dentures, visit your dentist immediately.

The difference between full and partial dentures.
The loss of a tooth or multiple teeth can be a devastating occurrence and has the potential to create a significant impact on the well-being of your mouth and subsequent overall health. Restricted ability to perform natural functions, a weakened jawbone, permanent damage to remaining teeth and an aesthetically lacking smile, are just a few of the changes which may occur after tooth loss.
An effective and popular solution to this problem can be found in the use of dentures – either in full or partial format.
A full denture is placed in the mouth after any remaining teeth have been removed and tissues have healed. Healing can take several months, during which time you are without teeth. The complete full denture replaces all the teeth in the mouth.
An immediate full denture is inserted immediately after the remaining teeth have been removed or all teeth lost, allowing the surrounding area of gum and tissue to heal whilst the denture is in place.
After tissue and gums have healed, the denture may need to be reshaped or relined as it becomes loose during the healing process.
Partial Dentures fill in the spaces where there are missing teeth and prevent other teeth from changing position. Partial Dentures rest on a metal framework that is attached to your natural remaining teeth. Crowns can sometimes be placed on some of you natural teeth and serve as anchors for the denture. Partial Dentures offer a removable alternative to bridges.
A new denture will not last forever as the mouth and face change shape and the denture will either have to be replaced or realigned.
There are different types of dentures depending on the individual need and variations on the structure are made in accordance to your specific requirements.
Here treatment to find the best type of denture for you, and we can advise on every aspect of your dental treatment, in the quest to find the most elegant solution to your problem. Full or partial dentures, upper or lower dentures, conventional or immediate dentures, we have the answer to your needs.
Dentures are artificial replacements used to replace teeth when you no longer have natural teeth. They are used by millions of people with acceptable results.
Immediate dentures are dentures that are inserted into a patient’s mouth on the same day or immediately after teeth are extracted. They are made by a dental lab from impressions or molds that are made before teeth are extracted. They work well for patients that can not wait three to six months for their gums to heal after extractions. They will require relining or replacement after six to 12 months after shrinkage and healing is complete.
Cusil Dentures are partial dentures with soft rubber or silicone gaskets placed around existing or remaining teeth to help hold the partial denture in place.
Overdentures are dentures that are made over existing teeth in the mouth. Usually, they are teeth that have been capped or crowned. They help secure the denture in place.
Implant Retained Dentures and Mini Implant Retained Dentures
Implant retained dentures are dentures that are secured in place by implants or attachments that have been surgically placed in a patient’s upper or lower jawbone to make the denture more secure. Mini implant retained dentures perform the same function, but are used for patients with smaller jawbones.
Duplicate, clone, spare. or embarrassment dentures are usually dentures made or molded from an existing denture and used for an emergency spare denture. They can be made in several different ways. The most inexpensive way is to mold or duplicate an existing denture. The cost for this is about 25% of the cost of making new dentures from an impression. No additional dentist appointment is required.
Anyone that has worn dentures is probably aware of the pain that they can cause. Most commonly, pain occurs in the first stages of denture wear, with the gum tissue of the mouth still sensitive from tooth removal, although discomfort and pain throughout denture use is common. Whatever pain dentures may bring the wearer, however, there are many available options to relieve the pain, aid in the healing of the mouth, and help prevent future pain. Even in later stages of denture-wearing, there are treatment options available to help relieve the pain and provide normal mouth function. Understanding how dentures work in the mouth and how personal behavior influences comfort or pain can greatly aid in understanding how best to treat denture pain.
The part of the mouth that often causes denture-wearers the greatest discomfort is the mucosa. The mucosa is the membrane lining the mouth and gums that help protect the mouth from irritants and helps the mouth absorb materials introduced orally. It is this membrane that is most easily irritated by dentures, and oral procedures such as tooth extraction are hard on the membranes of the mouth. It is this mucosa that really takes on the immediate stress of the dentures.
It is to this surface that the dentures adhere in the mouth. The mucosa covers the gums, with the dentures requiring so much suction to make a good hold. In the process, a mouth new to dentures can be unprepared for the surface contact, and the mucosa can take damage, be worn away, or be irritated, allowing pain to develop. The mucosa is the most prominent area of the mouth to take damage from dentures. Damage can be subtle, sometimes not even apparent, although injured tissue can lead to swelling, sensitivity, and sores, which can make denture wear excruciating.
A common cause of swelling is simple irritation. Some dentures can rub, causing sores or abrasions, and even slight irritation can cause the injured tissue to release histamine, which causes swelling. Increased swelling worsens denture fit and increases rubbing, turning pain into a difficult cycle to manage.
To best understand mouth pain, it helps to understand the membrane lining the mouth and gums. The mucosa varies in thickness throughout the mouth, from up to a couple millimeters thick to barely a fraction of a millimeter. Pressure from dentures wears on the mucosa, and where the membrane is the most thin is where pain will first flare up. There is less membrane to cushion the dentures, which can lead to abrasions or sores.
A major cause of pain in denture-wearers is uneven distribution, which includes a number of factors. One such factor is the bone structure of the mouth. No bones are the same from person to person. It is possible that underlying bones of the gums can have ridges or bumps, which can cause further wearing and thinning of the mucosa and gums. Where the membrane is thinnest, the bones are more prominent, and any rubbing of the dentures on that area can quickly cause discomfort, pain, and even injury as it wears down the tissue.
To protect denture-wearers from such discomfort, a thicker gel to adhere the dentures could be used. However, oral surgery is sometimes necessary to remove the problematic ridges of bone causing such discomfort. If experiencing such pain, a dentist should be consulted to determine the best option in course of treatment.
Another major issue are the size and height of the dentures. Anyone that has had a crown or even a filling knows that the size of the tooth is important. If a tooth is too high, biting or chewing can become painful, and in some cases, impossible. If dentures sit too high, or they don’t match your normal bite, this can cause stress on the gums, and the extra pressure can cause pain, swelling, and sores. This is especially important as chewing with uneven dentures or dentures that prevent an appropriate bite can cause even greater damage to the mouth and to the dentures. Wearers whose dentures prevent a normal bite should see their dentist to have them appropriately sized.
Similarly, a major factor in denture pain is one that be easily remedied – the dentures simply do not fit well. After tooth extraction, the structure of the gums and the mucosa are subject to change as the mouth adjusts. Dentures that fit previously may simply not fit as well anymore, causing slipping, rubbing, and other discomfort. This can also be attributed to age. As a patient ages, the structures of their mouth can change, including a thinning of the gums or the mucosa. A visit to a dentist can confirm if this is the case, or if there is some other cause of pain, and the dentures can be resized or remade if needed for a better fit.
Personal habits can also lead to pain. Those used to eating harder food may find such hard foods cause undue stress on the dentures, injuring the soft tissues of the gums and possibly causing them to rub. Eating softer foods to minimalize chewing and the force necessary to chew may help in relieving stress on the jaw and the gums, further reducing discomfort.
Many people new to dentures can also find themselves clenching or grinding their teeth, or chewing on the dentures. Such actions are not usually done intentionally. Grinding of the teeth is a common subconscious habit, and it’s natural to try to work out the feeling of a foreign object in the mouth. Learning to catch oneself in the act of grinding one’s teeth and training oneself against the involuntarily habit will help to relieve the undue pressure and stress on the mouth.
There are many ways to help prevent denture pain that wearers can do on their own. After first being fitted with dentures, sticking to softer foods will help in the adjustment process. It gives the tissues of the mouth, possibly sore and still adjusting after dental procedures, time to heal and get used to denture wear. Some softer foods include soft pasta, puddings, rice, soups, and stews.
Oral Hygiene – Relieve Denture Pain.
Oral hygiene is very important. While a person with a full set of dentures may no longer have to worry about cavities, bacteria will still build up in the mouth, and dentures provide an easily accessible bed for them to grow on. Dentures should be removed twice a day and brushed thoroughly with a toothbrush using warm water and a gentle cleaning soap. They are to be rinsed well before being returned to the mouth.
Another way to relieve denture pain is by means of a homemade mouthwash. Mix one tablespoon (1 tbsp) of peppermint leaves and two teaspoons (2 tsp) of crushed aniseed into two cups of boiling water. Cover and allow to sit for eight hours. Use a fine strainer to filter out large particles from the mouthwash, then add one teaspoon (1 tsp) of myrrh tincture, a preservative and an antiseptic. The mouthwash can be stored in a closable glass container. Rinsing with two tablespoons (2 tbsp) twice a day, shaking the mixture before each use, should help ease minor pain.
To help ease pain and also clean any sores, mix ½ a teaspoon of salt into ¼ a cup of warm water for gargling. Salt water is not to be swallowed.
Other ways to help prevent denture pain is to simply rest the mouth. Remove the dentures for a time every day – six hours at the least. This is most easily accomplished by removing them at night, giving the mouth time to mend and relax out of the confines of dentures and their adhesive. Massaging the gums with a fingertip or the soft bristles of a toothbrush – not hard or firm bristles – can help to ease pain. Also, stimulation of the gums in such a way encourages healing and helps toughen the surface of the gums, providing added support for dentures.
Dentures should be checked often and repaired often to ensure the best, most comfortable fit possible. Recommended examinations include having the dentures examined once a year, getting them relined and adjusted every two to three years, and having them replaced every five or six years.
If suffering from dental pain, upon visiting your dentist, wear the dentures for at least an hour before the appointment so the dentist can better see the source of irritation.
Over-the-counter anti-inflammatory pain medication can help, but a dentist should be consulted to help narrow down the source of the problem and eliminate it.
Dentures are prosthetic devices constructed to replace missing teeth, and which are supported by surrounding soft and hard tissues of the oral cavity. Conventional dentures are removable, however there are many different denture designs, some which rely on bonding or clasping onto teeth or dental implants. There are two main categories of dentures, depending on whether they are used to replace missing teeth on the mandibular arch or the maxillary arch.
Patients can become entirely edentulous (without teeth) due to many reasons, the most prevalent being removal because of dental disease typically relating to oral flora control, i.e. periodontal disease and tooth decay. Other reasons include tooth developmental defects caused by severe malnutrition, genetic defects such as Dentinogenesis imperfecta, trauma, or drug use.
Dentures can help patients in a number of ways:
1. Mastication – chewing ability is improved by replacing edentulous areas with denture teeth.
2. Aesthetics – the presence of teeth provide a natural facial appearance, and wearing a denture to replace missing teeth provides support for the lips and cheeks and corrects the collapsed appearance that occurs after losing teeth.
3. Phonetics – by replacing missing teeth, especially the anteriors, patients are better able to speak by improving pronunciation of those words containing sibilants or fricatives.
4. Self-Esteem – Patients feel better about themselves.
Types of dentures
Removable partial dentures
Removable partial dentures are for patients who are missing some of their teeth on a particular arch. Fixed partial dentures, also known as “crown and bridge”, are made from crowns that are fitted on the remaining teeth to act as abutments and pontics made from materials to resemble the missing teeth. Fixed bridges are more expensive than removable appliances but are more stable.
Conversely, complete dentures or full dentures are worn by patients who are missing all of the teeth in a single arch (i.e. the maxillary (upper) or mandibular (lower) arch).
Prosthodontic principles of dentures
Support is the principle that describes how well the underlying mucosa (oral tissues, including gums and the vestibules) keeps the denture from moving vertically towards the arch in question, and thus being excessively depressed and moving deeper into the arch. For the mandibular arch, this function is provided by the gingiva (gums) and the buccal shelf (region extending laterally (beside) from the posterior (back) ridges), whereas in the maxillary arch, the palate joins in to help support the denture. The larger the denture flanges (part of the denture that extends into the vestibule), the better the support. This last sentence requires comment and correction, it reveals some misunderstanding by the author as flanges usually provide stability and not support. Indeed, long flanges beyond the functional depth of the sulcus are a common error in denture construction, often (but not always) leading to movement in function.
Stability is the principle that describes how well the denture base is prevented from moving in the horizontal plane, and thus from sliding side to side or front and back. The more the denture base (pink material) runs in smooth and continuous contact with the edentulous ridge (the hill upon which the teeth used to reside, but now consists of only residual alveolar bone with overlying mucosa), the better the stability. Of course, the higher and broader the ridge, the better the stability will be, but this is usually just a result of patient anatomy, barring surgical intervention (bone grafts, etc.).
Retention is the principle that describes how well the denture is prevented from moving vertically in the opposite direction of insertion. The better the topographical mimicry of the intaglio (interior) surface of the denture base to the surface of the underlying mucosa, the better the retention will be (in removable partial dentures, the clasps are a major provider of retention), as surface tension, suction and just plain old friction will aid in keeping the denture base from breaking intimate contact with the mucosal surface. It is important to note that the most critical element in the retentive design of a full maxillary denture is a complete and total border seal (complete peripheral seal) in order to achieve ‘suction’. The border seal is composed of the edges of the anterior and lateral aspects AND the posterior palatal seal. The posterior palatal seal design is accomplished by covering the entire hard palate and extending not beyond the soft palate and ending 1–2 mm from the vibrating line.
As mentioned above, implant technology can vastly improve the patient’s denture-wearing experience by increasing stability and saving his or her bone from wearing away. Implant can also help with the retention factor. Instead of merely placing the implants to serve as blocking mechanism against the denture pushing on the alveolar bone, small retentive appliances can be attached to the implants that can then snap into a modified denture base to allow for tremendously increased retention. Options available include a metal hader bar or precision balls attachments, among other things.
Complications and recommendations.
The fabrication of a set of complete dentures is a challenge for any dentist, including those who are experienced. There are many axioms in the production of dentures that must be understood; ignorance of one axiom can lead to failure of the denture case. In the vast majority of cases, complete dentures should be comfortable soon after insertion, although almost always at least two adjustment visits will be necessary to remove sore spots. One of the most critical aspects of dentures is that the impression of the denture must be perfectly made and used with perfect technique to make a model of the patient’s edentulous (toothless) gums. The dentist must use a process called border molding to ensure that the denture flanges are properly extended. An array of problems may occur if the final impression of the denture is not made properly. It takes considerable patience and experience for a dentist to know how to make a denture, and for this reason it may be in the patient’s best interest to seek a specialist, either a prosthodontist or perhaps even a denturist, to make the denture. A general dentist may do a good job, but only if he or she is meticulous and usually he or she must be experienced.
The maxillary denture (the top denture) is usually relatively straightforward to manufacture so that it is stable without slippage.
A lower full denture should or must be supported by 2-4 implants placed in the lower jaw for support. A lower denture supported by 2-4 implants is a far superior product than a lower denture without implants, because
1) It is much more difficult to get adequate suction on the lower jaw.
2) The functioning of the tongue tends to break that suction, and
3) Without teeth the ridge tends to resorb and provides the denture less and less stability over time. It is routine to be able to bite into an apple or corn-on-the-cob with a lower denture anchored by implants. Without implants, it is quite difficult or even impossible to do so.
Some patients who believe they have “bad teeth” may think it is in their best interests to have all their teeth extracted and full dentures placed. However, statistics show that the majority of patients who actually receive this treatment wind up regretting they did so. This is because full dentures have only 10% of the chewing power of natural teeth, and it is difficult to get them fitted satisfactorily, particularly in the mandibular arch. Even if a patient retains one tooth, that will contribute to the denture’s stability. However, retention of just one or two teeth in the upper jaw does not contribute much to the overall stability of a denture, since a full upper denture tends to be very stable, in contrast to a full lower denture. It is thus advised that patients keep their natural teeth as long as possible, especially their lower teeth.

Since when does the Dentist actually make the denture? THE TECHNICIAN is the one who hand makes the denture!!! Any new prosthesis in the mouth is abnormal at first and takes around? 2 days to 2 weeks for the patient to adjust. I will temporarily affect the normal phonetics and mastication! (speech and chewing) Any new object in the mouth feels annoying and uncomfortable until the muscles in the mouth and face adjust to the prosthesis! I make them and I wear one so I know what Im talking about.
Unless the tongue is crowded by a incorrect bite or too much acrylic on the plate! Normally the speech is only very slightly changed and corrects in one day. The? dentist should ask you to talk normally and listen if there is and lisping etc when you talk. Sometime when the tryin stage is done in wax, phonetics should be checked. This isnt the case with a immediate and it will take time for the muscles in the mouth and face to relax and adjust to the prosthetics. Also the soft tissue to heal.
